In Black et al.1, Pamela S. Whitfield was omitted from the list of authors. The correct list of authors is David R. Black, Marcus H. Mendenhall, Pamela S. Whitfield, Donald Windover, Albert Henins, James Filliben and James P. Cline. The article has been corrected to reflect the correct authorship.
The authors would also like to add the following acknowledgement of support from the Oak Ridge facility, which was inadvertently omitted from the original publication: A portion of this research used resources at the High Flux Isotope Reactor and Spallation Neutron Source, a DOE Office of Science User Facility operated by the Oak Ridge National Laboratory.
The authors apologize for these errors.
